The Hasegawa-Mima equation for a quasi-two-dimensional electrostatic drift wave' is generalized to include arbitrary distributions of 1.he equilibrium electrostatic poten-tial and the density and temperature of plasma. It is shown that the spatialdependence of the equilibrium density distribution plays a decisive role in determin-ing the behavior of the steady vortex solution, that is, whether it is a single soliton orpair-solitons, etc. The relation between the drift wave equation and the barotropicequation for Rossby waves is discussed, and, in particular, a remark is made on Petviashvili's equation which has an additional nonliruear term proportional to the fern-perature gradient.
